2013 Toyota Prius C Problems

Brake master cylinder failure.

My 2013 Toyota Prius has a failed inverter/converter assembly, including the Intelligent Power Module (IPM). This component is critical for vehicle operation and designed to last the life of the car. Premature IPM shorting and inverter failure is a known defect acknowledged by Toyota through multiple recalls and service campaigns for other VINs with the same part number. My vehicle is giving codes P0A94 and P0A1A which are also listed in the recalls for other Prius models of similar age. My vehicle experiences the same failure, yet Toyota has denied goodwill coverage, claiming “insufficient service history.” Routine maintenance like oil changes and brake inspections does not affect this component, making the denial unreasonable. There is nothing to service on the inverter. This defect poses a serious safety risk, sudden inverter failure caused total loss of power while driving and loss of power steering, it was difficult to pull my car off the road. This poses a danger to drivers, passengers, and others on the road. Toyota’s exclusion of my VIN from coverage leaves me financially responsible for a known safety defect. I request NHTSA to investigate Toyota’s handling of inverter/IPM failures, the denial of goodwill assistance for affected VINs, and ensure that Toyota addresses this life-threatening defect consistently across all affected vehicles instead of narrowing the scope on who gets coverage when this is a dangerous electrical malfunction.

Brake master cylinder failure.

Car suddenly needed a jump start and again after a day or two of non-use. On the third day Brakes, ABS and traction control warnings were lighted up and remains. Brakes are mostly ineffective. My own scan returns the code C1252 and C1256 that says brake booster system failing. Took it to the dealer who charged $290 again to scan and came up with failed brake booster and pump assembly. The dealers is quoting total $4000 to fix. Toyota Customer Support Program Bulletin dated 8/2018 and revised on 8/2019 extends the warranty on for this issue (for Toyota Prius C 2013) for 10 years or 150000 miles. I was never informed by Toyota or the seller (Stevens Creek Toyota, San Jose CA) about this defect under warranty that I could have gotten repaired well before the dead line of 10 years. Now Both Toyota or the dealer's service department refuse to bear the repair cost.

The contact owns a 2013 Toyota Prius C. The contact stated that while his wife was attempting to cold-start the vehicle, the vehicle failed to start. The contact stated that on several occasions the vehicle was started; however, the instrument cluster and other electrical devices failed to operate as needed. The contact replaced the auxiliary battery. The vehicle was repaired, but the failure reoccurred, and the vehicle needed to be jump-started. The vehicle was not taken to a local dealer or independent mechanic to be diagnosed or repaired. The contact researched online and related the failure to NHTSA Campaign Number: 20V369000 (Hybrid Propulsion System); however, the VIN was not included in the recall. The manufacturer was not informed of the failure. The failure mileage was approximately 150,000.

The contact owns a 2013 Toyota Prius C. The contact stated that while driving at 25 MPH, the vehicle stalled and failed to restart. The contact stated that he and his wife were in the vehicle during the failure, and the vehicle was almost crashed into. The contact stated that he and his wife were left stranded in oncoming traffic. The vehicle was towed to the dealer, where it was diagnosed that there was a computer failure and that the inverter converter assembly needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 75,421.

failure of the Intelligent Power Module (IPM) within the inverter assembly

My vehicle has under 150,000 miles. I was driving on the highway and my Prius lost power and left me on the side of the road. I took it to Toyota to run a diagnostic in Elk Grove Ca. I was told the ipm inverter, control computer had to be replaced and it would cost me $5,200.00. This is a real disappointment because I don’t have this money to fix the vehicle.

There was a driver side collision and the airbags did not deploy. Brakes do not slowly apply they slam down causing vehicle to slide/skid in emergency braking, ABS does not function properly. The dealership recently did an appraisal (4/2/25) on the vehicle that states “Lost communication with side airbag sensor LH, Side airbag sensor LH initialization incomplete, front speed sensor RH & LH circuit, and D- Door Motor ECU communication stop”. Insurance company inspected vehicle after crash, and there was a police report filed. There were no warning indicators prior to incident or after.

I was going on my way to work on the freeway at approximately 65 miles per hour, suddenly I felt as if my car shut off will driving and I lost power. I pressed on the gas Pedal as I was pulled into the emergency lane to the right of the freeway, the gas pedal did not work. I pulled to the side and I shut the car off. I waited about 20 minutes and I turned the car back on.

So, long story short: for months now, the engine light goes on and off. Whenever it goes on, I go to Autozone or O'Reilly's to get the codes read. It's always the same code: P261B. So I got the coolant pump replaced. The same thing happens! I'd bet there is nothing wrong with the pump, so why am I getting that same code? I'll be happy to send it to you if you want to test it....

HYBRID WARNING LIGHT COMES ON OUT OF NOWHERE. CODE 3107: LOST COMMUNICATION BETWEEN SRS ECU AND POWER MANAGEMENT ECU. ALL WIRES ARE OTHERWISE GOOD AND NO CORROSION IS APPARENT. THIS MISCOMMUNICATION MEANS THAT THE AIRBAGS ARE NOT WORKING PROPERLY. BATTERY IS HEALTHY ACCORDING TO TOYOTA DEALERSHIP. HYBRID WARNING LIGHT COMES ON INTERMITENTLY TO SHOW WHEN MISCOMMUNICATION IS HAPPENING.

THIS APPEARS TO BE A SAFETY ISSUE. ALSO I WAS TOLD CAR WAS DAMAGED, NOT IN MAJOR ACCIDENT. HAS SIGNS OF HEAVY DAMAGE FROM 3 ACCIDENTS. IT ONLY HAS 54,XXX MILES ON A 2013 PRIUS C.

According to Toyota Dealership, "WILL NEED TO REPLACE (MG1) HV TRANSAXLE UNIT AS 1ST STEP IN ORDER TO TO BE ABLE TO PROCEED WITH DIAGNOSE AND CHECKED FOR ANY OTHER SHORTED COMPONENTS". Vehicle is available for inspection. Vehicle was being driven on a city street towards a red light when the vehicle experienced a jolt and lost complete acceleration power and a "Check Hybrid System" was displayed on the dashboard. Luckily all vehicles behind were already coming to a stop for the red light, otherwise, the safety of my family and myself may have been put in more serious harm. Vehicle able to crawl to a nearby gas station. Attempted to use remaining battery power to drive back to residence nearby, but lost all battery power/function and puled into a bus lane where vehicle was towed from. There were no warning lights or messages displayed prior to the incident. Toyota Dealership performed DTC verification 3 times and found to verify P0A94 detail code 172 is the persistent DTC when memory is cleared. They also inspected the vehicle for concern and were able to verify Check Engine Light is ON, vehicle is on "Limp Mode" and does not "Ready ON". The vehicle has not been inspected by anyone else other than the Toyota Dealership.

TOYOTA IS TRYING TO COVER UP THE TRUE NUMBER OF VEHICLES SUBJECT TO THE HYBRID SYSTEM RECALL.. TOYOTA CLAIMS THIS VEHICLE IS NOT THE SUBJECT OF RECALL, YET THE VEHICLE DISPLAYS ALL THE SYMPTOMS DESCRIBED IN THE RECALL.. 1.) THE VEHICLE WAS IN MOTION AT FREEWAY SPEED ON WESTBOUND HWY 92 ON 12/27/2020 AT APPROXIMATELY 6:30PM 2.) THE VEHICLE LOST ALL POWER.. DASHBOARD LIGHTS CAME ON.. ERROR MESSAGE SAID "HYBRID SYSTEM FAILURE" 3.) POWER TO BRAKING AND STEERING REMAINED 4.) VEHICLE WENT OFF THE FREEWAY, WITH NO POWER, DOWN AN EXIT RAMP, AND CAME TO A STOP, LUCKILY, IN A LEGAL PARKING PLACE, AT THE CURB ON DE ANZA BLVD.. THIS IS WHAT TOYOTA SAID PUBLICLY: 'THE INVOLVED VEHICLES WERE DESIGNED TO ENTER A FAILSAFE DRIVING MODE IN RESPONSE TO CERTAIN HYBRID SYSTEM FAULTS', THE AUTOMAKER EXPLAINED. 'TOYOTA HAS FOUND THAT IN RARE SITUATIONS, THE VEHICLE MAY NOT ENTER A FAILSAFE DRIVING MODE AS INTENDED. IF THIS OCCURS, THE VEHICLE COULD LOSE POWER AND STALL. WHILE POWER STEERING AND BRAKING WOULD REMAIN OPERATIONAL, A VEHICLE STALL WHILE DRIVING AT HIGHER SPEEDS COULD INCREASE THE RISK OF A CRASH.'

Immobilized failure due to combination of brake hose failure preventing hybrid control/shift actuator. Hybrid steering lock became disengaged and could not communicate with the certification ecu due constant power being disabled due to complete main body failure. Hybrid system cannot go back into park however ecm side did. Ecm was not receiving power as dealer coded main body as a plug in hybrid effectively disabling fuel systems (including emissions/fuel safety) causing full misclassification in the smart key certification process. Car starts, goes into ready and disables LIN comms alongside cutting main relay due to tailgate and fuel constant powers being cut while driving.

I GOT IN MY CAR, WHICH WAS PARKED IN FRONT OF MY HOUSE, AT 6:15 PM AFTER A SUNNY, WARM DAY. WHEN I CLOSED THE DRIVER'S SIDE DOOR, THE BACK WINDOW SHATTERED WITH AN EXTREMELY LOUD BANG. THE MAJORITY OF THE GLASS WAS OUTSIDE THE CAR, ON THE STREET. WHEN I SPOKE TO THE CLAIMS ADJUSTER FOR MY INSURANCE COMPANY AFTER HE EXAMINED THE CAR, HE HAD SOME THEORIES ABOUT WHAT HAPPENED BUT NOTHING CONCRETE. HE MENTIONED THAT PERHAPS THE INTERIOR VENTS WERE BLOCKED WHICH COULD HAVE CAUSED PRESSURE INSIDE THE CAR TO SHATTER THE BACK WINDOW, SO THE BODY SHOP GUYS EXAMINED THOSE VENTS. THEY FOUND THEM TO BE CLEAR. BOTH THE CLAIMS ADJUSTER AND THE BODY SHOP GUYS ASKED ME IF THERE HAD BEEN ANY DAMAGE TO THE GLASS ON BACK WINDOW BEFORE THE INCIDENT, AND I SAID THAT I HAD NOT NOTICED ANY. *TR
